LogiCool InRak Data Centre Cooling 10-60kW: Highly efficient and resilient The LogiCool InRak is an efficient in-row cooling solution for high density data centre applications. Positioned next to a rack or within a row of server cabinets, the InRak directs air horizontally to the front of the server racks. The InRak delivers complete confidence, with in-built resilience and excellent efficiencies, lifting the InRak’s EER to 90.3 during part load operation. Providing industry-leading cooling for its footprint, the InRak offers the ultimate in scalable solutions for the modern data centre. It includes a top connection for rooms without a floor void and delivers even greater efficiency when combined with Airedale’s latest technology free-cooling chillers.

increased efficiency and
uptime
• Aisle pressure control
managing pressure
between the hot and cold
aisle
• Automatic transfer switch (option) plus controller backup
• Hot swappable fans allowing fan assembly to be replaced while unit is
running

5. Operation and energy saving
• Compact design for increased cooling
per m2
• Dew point control
• Air filtration
• EMC compliance
• 66% energy saving p.a. with EC fan*
• EC inverter compressor for precise
control and high part load efficiency
*Compared with a conventional CRAC unit

6. Key Feature:
Improved efficiency through aisle containment

7. Key Feature:
Improved efficiency through aisle containment
• Can be integrated into a traditional hot or cold
aisle system
• In aisle containment, the InRak’s performance
is significantly increased
• Risk of cold air mixing with rejected hot air
greatly decreased
• Reduces the need for very low supply
temperatures, vastly improving efficiency

8. Key Feature: EC inverter driven compressors

9. Key Feature: EC inverter driven compressors

10. Key Feature: EC inverter driven compressors
Variable capacity control
•InRak features two scroll compressors in one circuit
• Fixed speed compressor working
• EC latest technology 20-120 rps inverter compressor
•Fully modulated cooling performance from 17 – 100%
•Variable speed control allows InRak to to exactly match cooling demand
•Inverter compressor has a 10% equivalent starting current
•Designed for minimal sound output and optimal efficiency

11. Key feature: EC centrifugal fans

12. Key feature: EC centrifugal fans
70% more efficient than AC fan at part load
•Energy costs can be significantly reduced
when cooling equipment operates at part load
•Engineered with a very low air flow resistance
•Latest EC fan technology which delivers greatly
enhanced fan efficiency, particularly at part load,
lifting EER to 90.3 (n+1)

13. Key option: n+1 fan configuration

14. Key option: n+1 fan configuration
Increased efficiency and uptime
•Enhanced by smart control logic and EC fan technology,
InRak has built-in redundancy and excellent part load
efficiencies
•Gives an EER increase from 58.0(n) to 90.3(n+1)
•Designed so that all four fans run at 75% during normal
operation. If one fan fails, the other three speed up to 100%
to provide the same amount of cooling and maintain
temperature control
•Hot swappable fan management

15. Key option: integration with a free-cooling chiller

16. Key option: integration with a free-cooling chiller
Reducing whole life costs
•InRak can be matched with an Airedale free-
cooling chiller
•Airedale free-cooling chillers operate with
as little as 1°C differential between ambient
and return fluid temperatures
•A large proportion of the year can be spent in free-cooling mode
•In the 24/7 environment of a data centre, a free-cooling chiller will use very
little mechanical cooling

17. Using heat to increase free-cooling
• High water temperature capabilities within
the whole range of Airedale free-cooling
chillers raises the free-cooling threshold
• When linked with InRak in a 24/7 data centre
with typical hot aisle containment, over 95%
of the year can be spent with free-cooling
active – giving you exceptional return on
investment
One kilowatt of power saved every
hour 24/7, represents a saving of
£876* a year, equivalent to over 4
tonnes of CO2
* £0.10/kWh
